The few lines of code I've added in fixes this problem: The problem is that the mode will change to Discrete Only after certain apps which use Core Graphics close, such as Chrome or iOS Simulator. I have been a fan of your app for a long time, using it to force the Integrated Only mode. Seeing as most of the issues seem to be due to the dGPU would you just recommend getting a MacBook Air instead (or the 14 inch when it comes out) and selling the 16? Seeing as Apple hasn’t even acknowledged this is a problem I don’t see a fix coming at all until the next generation of machines.I'm a 2010 MBP user. ![]() It seems things aren’t too bad in that mode correct? But, I do need two displays regularly, including the webcam, so that means the machine will heat up especially with video conferencing (Zoom seems not bad but had a WebEx meeting and it got quite toasty). I’m fine using it in clamshell mode a large portion of the time. I do worry about the machine getting hotter than 70 C on a regular basis doing regular tasks like browsing and email. I don’t really care that much about fan noise. ![]() I really would like a desktop workstation for ergonomics and better productivity, including dual screens. Also the 15-16 inch form factor only is available as a “Pro.” I personally would still have my 2014 MBP but I had to give it to my niece to do her online schoolwork because of COVID. I, like I feel a large number of “pro” laptop owners (especially in the medical field like me) don’t necessarily need the power of the machine but bought it based on reputation, expecting a reliable and long lasting device like all pre-2016 MBPs. Some light photo editing (Lightroom) as a hobby not for work. I use my MBP mostly for productivity with multitasking (video conferencing, web, excel, word running simultaneously). Now we are faced with having to make several compromises (I.e. ![]() They used to be no compromise machines that you paid a premium for. in that case everyone is better off getting a windows laptop at a significantly lower price. They don’t “just work” anymore and when I’m hearing CPU temps getting up to 100 C I’m seriously doubting the longevity of these machines. They’ve become an afterthought to the iPads/iPhones/watches, etc. I’m thinking this might be my last Apple laptop. As a stand alone laptop it’s been a good machine though. I was hoping to set up a desktop workstation with the MBP 16 but boy am I glad that I did my research and discovered this thread. You'll need to wait at least a generation for the chipsets to become more efficient for that. There's not going to be a fix that makes the more powerful GPU draw the same power as the less powerful GPU. OR they can purchase a new MBP with a more powerful GPU, which will draw more power when active. ![]() My older Radeon Pro 455 idles at 5-6 W and uses 10 W to power the displays.īuyers are left with choices: they can purchase an older MBP with a less powerful GPU, which will of course draw less power when active. The older AMD chips were less powerful, and therefore drew less power. The difference between 5-6 W and 18 W is just the difference between the AMD chip idling and powering the displays.ĪMD chips in older MBPs are used in the same way: they run the displays when the computer is open and they idle in clamshell mode. With the computer open + external monitor, the OS runs the displays with the AMD chip, which requires about 18 W for those tasks. With the computer in clamshell mode and an external monitor, the external display is run by the integrated graphics chip, and so the AMD discrete graphics chip idles at about 5-6 W. From what I can tell, there's no big mystery here.
